BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a fitness sporting apparatus, and more particularly to a rotatable Swiss-ball AB (abdominal) trainer.

2. Description of Prior Art

Along with the continuous improvement of the life level of the people, various fitness exercises are widely popularized, meanwhile the various fitness sporting apparatus as assistant tools of fitness sport have made considerable headway, such like the innovated various styles of running machines, weightlifting, chest developers, rowing machines, sit-up boards, exercise balls (Swiss-ball) and so on, are came out in the market. Among of them, the abdominal fitness apparatuses are in good grace of the people bored by abdominal shape problems.

In accordance with the conventional technology, the apparatuses used for shaping abdomen simplistic, such as said exercise ball is put on the ground or leaned against some places for location so as not to carry out its all functions, in the same case, the sit-up boards have relative static, rigid and big volume shortcomings so that they are inconvenient for storing and transportation.

Therefore, for overcoming the shortcomings of the conventional sit-up boards and the exercise ball, a sport product having soft of the exercise ball and sit-up board's function is designed, meanwhile it also has smaller volume for storing, and movable for meeting the necessary of the user features, so the present invention comes out.

OBJECTS AND SUMMARY OF THE INVENTION

It is therefore a main object of the present invention to provide a rotatable Swiss-ball AB trainer facilitating to make various exercises, it also has foldable, small volume features for apt to package and transport and store.

The second object of the present invention is to provide a rotatable Swiss-ball AB trainer convenience for use.

For achieving the objects depicted above, a rotatable Swiss-ball AB trainer of the present invention is typically comprised of a frame and an exercise ball, wherein said frame is constructed of a support and a triangle stand, said exercise ball is mounted on the foldable triangle stand.

Said foldable triangle stand is consisted of side bars, rear carriage and tilting bars, said side bar is connected to the support with one end, and another end of the side bar is connected to the top end of the rear carriage via the tilting bar.

Said tilting bar is a two-bar linkage located on the both ends with bolts respectively.

Said side bar and the support are attached with a strut bracing.

Said strut bracing is a bar located by a bolt on one end and a latch on another end.

Said rear carriage is a U-shaped bar.

Said rear carriage is attached with a handle on each top end respectively.

Said foldable triangle is consisted of side bars, rear carriage and cross pivoting connectors, said side bar is connected to the support with one end, and another end of the side bar is connected to the top end of the rear carriage via the cross pivoting connector crossly located by a latch.

Said support is constructed of ground-based pipes and hook pipes, within said hook pipe is in telescopiform.

Said exercise ball is an inflatable ball.

As adopting the project depicted above, the present invention has following advantages comparing with the prior art:

-   -   1. due to the foldable triangle stand, it can be folded up so as         to reduce the volume of the frame, further to the whole AB         trainer in convenience of packaging, transporting or storing;     -   2. due to the hook pipe attached on the support, the feet of         exerciser can be hooked on and located facilitating to         operation;     -   3. Due to the handles formed on the top of the rear carriage,         the user can hold on as sitting down or up conveniently so that         the action is smooth and safety.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

Referring to FIG. 1 and FIG. 2, a rotatable exercise ball AB trainer provided by the present invention is comprised of a frame 1, a exercise ball 2.

Said frame 1 is constructed of a support 11 and a triangle stand 12.

Said exercise ball 2 is mounted on the foldable triangle stand 12 via a tube 16 passing through said exercise ball 2 and a securing bar 15 fitting into the inside of the tube 16 by securing the securing bar 15 on the both top ends of the triangle stand 12 crossly with the nuts 150 respectively.

Said triangle stand 12 is designed into foldable. The structure, as shown in FIG. 1, is constructed of side bars 121, a rear carriage 122 and tilting bars 123, said side bar 121 is connected to the support 11 with one end via a pivoting pin 129, and a strut bracing 124 is attached beyond the pivoting connection of the side bar 121 and the support 11, therein said strut bracing 124 being a bar is located on the support 11 with one end by a latch 131, and with another end on the side bar 121 by a bolt 130; and another end of the side bar 121 is connected to the top end of the rear carriage 122 via the securing bar 15 by gearing the nuts 150 in the threaded ends of the securing bar 15, and the tilting bar 123 being a foldable two-bar linkage is attached on between the side bar 121 and the rear carriage 122 by locating the both ends with bolts 130, in the same way, said tilting bar 123 also can be a bar as same as the strut bracing 124. Said rear carriage 122 can be shaped in U-shaped, or other shapes. As tending to fold up, just need to pull out the latches 131 locking the strut bracings 124 from the locking positions respectively, and to bend the tilting bars 123 (two-bar linkage) to release the location positions of the strut bracings 124 and the tilting bars 123, so that the rear carriage 122, the side bars 121 and the support 11 can be folded up conveniently for retracting the triangle stand 12 and the frame 1. In this way, the volume of the whole AB trainer can be reduced greatly for packaging, transporting and storing easily. The folding structure of said triangle stand 12 also can be in other styles, and the tilting bar 123 also can be in other mechanism, here will not instantiate in detail further.

Referring to FIG. 3 to FIG. 5, another preferred embodiment of the present invention is typically comprised of a frame 1 and an exercise ball 2, wherein said frame 1 is constructed of a support 11 and a triangle stand 12, and said exercise ball 2 is mounted on the foldable triangle stand 12. The differences of the embodiment from the first embodiment is that the triangle stand 12 is constructed of side bars 121, a rear carriage 122 and triangle connectors 125, said side bar 121 is connected to the support 11 with one end via a pivoting pin 129, and a strut bracing 134 is attached between the pivoting connection of the side bar 121 and the support 11, therein said strut bracing 134 being a bar bended the both ends into a long folding head and a short folding head respectively is located on the coordinating holes of the support 11 and the side bar 121 by plugging in separately; and another end of the side bar 121 is pivoted on the side of the triangle connector 125 with a rivet 126, for locating the side bar 121 on the triangle connector 125 relatively, a latching pin 127 is employed for plugging into the locating holes 128 respectively drilled on this end of the side bar 121 and the coordinated end of the triangle connector 125, the top end of the rear carriage 122 is fit into the inside of the housing hole built on the other end of the triangle connector 125, and riveted on by a rivet 126, or via two rivets the top end of the rear carriage 122 is directly fixed on the other side of the triangle connector 125. As tending to fold up, just need to pull out the latching pins 127 from the locking locating holes 128 respectively, so that the side bars 121 can be rotatable relative to the triangle connector 125, as shown in FIG. 5, for folding up conveniently to reducing the volume as same as the above-described in the first embodiment, it will not be described again.

For further reducing the volume of the whole AB trainer, the exercise ball 2 is designed into an inflatable ball, so that the inflated ball can be used in exercising, and the bled ball is in convenience of packaging, transporting and storing with the smaller volume.

Said support 11 is constructed of ground-based pipes and hook pipes 13, within said hook pipe is in telescopiform for locating the feet of user and adjusting the size according to the necessary; said rear carriage (U-shaped) 122 is attached with a handle 14 on each top end respectively for holding on by the user as sitting down or up conveniently.
